RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including asleep. Try it out:
// Require asleep
var asleep = require("asleep");
// A counter
var co = 1;
// A loop that works like an interval
while(1){
console.log("Hi there " + co++);
await asleep(2000);
}
